How to Set Up a Virtual Background — Step-by-Step for Every Platform

Every platform buries the virtual background setting somewhere slightly different, which is why "how to set up a virtual background" is one of the most-searched video call questions — even among people who use these apps every day. Below are exact step-by-step instructions for each major platform, followed by the one factor that most guides skip entirely.

Zoom

Zoom has the most mature virtual background feature and the most placement options. These steps work for Zoom desktop (Windows and Mac). Mobile steps are at the end of this section.

Before a call (recommended)

1. Open Zoom and click the gear icon (Settings) in the top-right corner.
2. In the left panel, select Background & Effects.
3. Click the Virtual Background tab if it isn't already selected.
4. Click the + button (Add image or video) and select your downloaded background file.
5. Click your newly added background to apply it — it will be used for your next call automatically.

During a call

1. Click the ^ arrow next to your video button in the toolbar.
2. Select Choose Virtual Background.
3. Click + to add a new image, or click an existing one to apply it immediately.

On Zoom mobile (iOS/Android)

1. While in a call, tap More (three dots) in the toolbar.
2. Tap Virtual Background.
3. Tap + to upload an image from your camera roll or files.

Microsoft Teams

Teams calls these "background effects" rather than virtual backgrounds. The upload path changed slightly in the New Teams (2024) client — both versions are covered below.

Before joining a call (join screen)

1. On the pre-join screen, look for Background effects (below your video preview).
2. The panel opens on the right side. Scroll down to find Add new.
3. Click Add new, select your image file, and it will appear in the panel.
4. Click your uploaded image to apply it, then click Join now.

During a call

1. Click the three-dot menu (More) in the call toolbar.
2. Select Video effects and avatars (or Background effects in older Teams).
3. Click Add new and upload your image.
4. Click your background to apply it — the change takes effect immediately.

Google Meet

Google Meet added persistent custom backgrounds in 2023 — you no longer need to re-upload each call. Custom backgrounds are available on personal Google accounts and Google Workspace accounts.

Before joining a call

1. On the pre-join screen, click Apply visual effects (below your video preview).
2. Scroll to the bottom of the backgrounds panel and click Upload a background (the + icon).
3. Select your image file. It will appear in your backgrounds panel.
4. Click your uploaded background to apply it before joining.

During a call

1. Click More options (⋮) in the call toolbar.
2. Select Apply visual effects.
3. Scroll to the bottom of the panel and click the + upload icon to add a new image.
4. Click your background to apply it — it changes immediately without interrupting the call.

Cisco Webex

Webex supports custom virtual backgrounds on the desktop app (Windows and Mac). The setting is found in your profile preferences rather than during call setup.

1. Open Webex and click your profile picture (top-right), then Settings.
2. Click Video in the left panel.
3. Under Virtual background, click + or Add and select your image.
4. Your uploaded background is now available at the start of each call via the background selector.

Platform comparison at a glance

Why the background image matters more than the settings

The most common complaint after setting up a virtual background is that it looks fake, pixelated, or that parts of the person keep disappearing. The setup steps are rarely the cause — the issue is almost always the background image itself.

Here's what makes a virtual background work well technically:

• Correct aspect ratio. All four platforms expect a 16:9 image. Use a 1920×1080 or higher image — never a portrait-orientation photo or a square image. Wrong ratios cause the background to stretch, crop, or tile.
• Depth cues. Images that look like a real physical space (depth of field, ambient lighting, perspective) look far more convincing than flat illustrations, gradient patterns, or stock photo composites. Your camera's AI blurs the edges of your silhouette, and a flat background makes that blurring immediately obvious.
• Neutral, non-distracting content. Busy backgrounds — lots of movement, text, bright colours, complex patterns — fight for attention. The best backgrounds read as a coherent space and then fade into the background of people's awareness.
• Resolution. Platforms compress your video stream before sending it. A higher-resolution source image (2912×1632 or higher) retains more visible detail after compression compared to a standard 1080p image.

Stock photo sites were built for print and marketing, not video calls. Their images are often square or portrait format, overly bright, or compositionally wrong for appearing behind a person. Backgrounds designed specifically for video calls — composed at 16:9 with appropriate depth and lighting — consistently look better without any other changes to your setup.
